Free owners manual at jeep.com bottom of page, owners/service manuals.
Every thread that mentions wkjeeps.com has this info. Does it discredit the entire site? Have you contacted them to have it changed?

I've done some reading thanks to another post, and anything to do with flow on the 5.7 Hemi other than heads is "snake oil" as stated previously. Noise makers, that is about it. Your better off putting your money into proper maintenance before upgrades that will simply look/sound cool. To each his own, nonetheless.

Read into yourself, search 5.7 hemi flow rates.

I noticed my sunroof was out of calibration because i could get a better seal on it if I pushed the vent button and then stopped it on its way "up" to vent position. When I re calibrated it my sunroof stopped leaking.

Every thread? No and no. It's advice so others may not have to redo maintenance like I have due to incorrect information.

Having two issue with the Jeep I'm having trouble being sure were to start
1) seems to misfire or hesitate between 40-60 mph does not try to stall or idle weird at this time and no codes
note: has new spark plugs gapped accordingly
2) since installing new trans lines and doing a trans flush I have noticed a hard down shift when coming to a stop several times now.
- need to go on a highway drive and then check fluid did the 15 minute drive maybe I am a little off?

Leaning toward doing the PCV and TPS, I well replace the PCV regardless but am I on track with a TPS? or should I do a throttle body cleaning (it looks ok) or the EGR?

Did you check for codes or are you saying that because no 'engine light' has come on?

Was the jeep hessitating before you started maintenance? If not then i would go back and look at what you did. double check wires tight and Plugs tight and gapped properly ( could have bumped an electrode accidentally and closed the gap).Or maybe you could have moved a vacuum line and it's leaking now ..

Trans - flushes are not recomended by Jeep . did you use ATF+4 (very important .Global or any other type of fluid is no good) . The PCM and TCM is adaptive , so you could try disconnecting the battery to erase the memory and then take it out for a good drive . It will probably drive and shift like crap for a while though.
